Description

[Detailed description of the invention] This invention allows two or three types of frames to be attached to a column with casters attached to the lower end by an extremely simple operation without using any parts or tools. By this,
For example, it relates to an assembly type transport vehicle that can carry a large number of trays containing a large number of small items, and can be disassembled for easy transport or storage when not in use. This will be explained in detail based on the drawings.

Casters 2 are attached to the lower end of each long pipe-shaped support 1.

The lower horizontal frame A having a rectangular shape faces the inner surface of the central part of the vertical pipe columns 3 of equal diameter and length at the four corners in the front-rear direction,
It is formed by connecting L-shaped rails 4, 4 which are parallel to each other and have the same height, and horizontal rods 5, 5 which face in the left-right direction below the rails, and each tube column 3 is externally fitted onto the column 1.

Reference numeral 6 denotes a connecting rod having a U-shape on the top surface, and as shown in FIG. 3, near the tip of each horizontal parallel piece 6a, there is a stepped portion 6b that once faces downward and then bends to become horizontal. Similarly, a cylindrical roller 7 is pivotally fitted to the center piece 6C.

The connecting rod 6 connects its parallel pieces 5 a , 5 a to each rail 4
After drilling holes near both front and rear ends of the horizontal piece 4a,
After passing through the pair of left and right through holes from above to the stepped portion 6b, the roller 7 is detachably attached horizontally, and the upper surface of the roller 7 is located slightly higher than the horizontal piece 4a.

B is a vertical frame, and the pipe posts 8, 8, which have the same diameter as the pipe post 3 and are longer than the pipe post 3, are arranged horizontally and parallel to each other with a predetermined interval above and below the rail 4. They are formed by connecting rails 9 of the same shape and length.

The tube columns 8 of the left and right vertical frames B are fitted directly above the tube columns 3 on the left column 1 and the right column 1.

A connecting rod 10 similar to the connecting rod 6 is attached between the front end and the rear end of the left and right rails 9, 9, and each connecting rod 10 has a roller 11 similar to the roller 7. It is pivot-fitted.

C is an upper horizontal frame body having almost the same configuration as the lower horizontal frame body A, and the inside surface of the center part of the four vertical corner tube columns 12 having the same diameter and length as the tube columns 3 is connected to the rail 4. They are connected by L-shaped rails 13.13 facing in the same front-rear direction, and both the rear tube columns 12 and the front tube columns 12 are connected by a horizontal rod 14 similar to the horizontal rod 5 and a U-shaped upper surface. The handles 15 are connected to each other with a handle 15 projecting outward.

Each tube column 12 of the upper horizontal frame C is externally fitted directly above the tube column 8 on the column 1, and the upper end of the tube column 12 has a
A closure plug 16 is fitted.

A connecting rod 17 similar to the connecting rod 6 described above is attached between the front end and the rear end of both rails 13, and the connecting rod 17 includes the following:
A roller 18 similar to the roller 7 described above is pivotally fitted.

In the transport vehicle having the above-mentioned configuration, the pipe posts 12 and 3 of the horizontal frames C and A are fitted onto the upper and lower ends of each support 1, respectively, and the pipe posts 8 of the left and right vertical frames B in the middle are Since they are connected via the rails 9 and the connecting rods 10, they are extremely strong and the support columns 1 do not bend. A tray 19 containing small items can be placed on the tray 19 for transportation or display.

At this time, since the upper surface of each roller 7, 11, 18 is located slightly higher than each rail 4, 9, 13,
There is no fear that the tray 19 will fall, and the tray 19 can be taken in and out easily.

Further, as already clear from the above, the present transport vehicle is very easy to assemble and disassemble, and is convenient because it can be disassembled for transportation or storage when not in use.

In addition, in the above-mentioned embodiment, the rail 9 of the vertical frame B
Although the rails 9 can be provided with a desired number of stages, a plurality of vertical frames B can be installed between the horizontal frames A and C depending on the case.

Furthermore, in place of the upper horizontal frame C, a horizontal frame A may be installed; in this case, there is no handle 15, which is somewhat inconvenient when moving the transport vehicle, but the advantage is that the number of parts can be reduced. There is.

Claims (1)

[Scope of utility model registration request] A column with casters attached to the lower end and pipe columns of equal diameter and length that are perpendicular to the four corners are paired on the left and right, facing in the front-back direction, and rails of equal length that are parallel to each other, and facing in the left-right direction. A rectangular upper and lower horizontal rain frame body formed by connecting with horizontal rods and having a pipe post fitted onto the above-mentioned support post forms a front and rear pair, faces in the up-down direction, and is connected with the above-mentioned pipe post. It is formed by connecting the important points of the diameter pipe columns with rails of the same shape and length as the above-mentioned rails, facing in the front-rear direction, having a predetermined interval above and below, and parallel to each other,
and a pipe column is removably attached to a pair of left and right vertical frames fitted between the upper and lower horizontal frames of the column, and to an end of a pair of left and right rails of each frame, An assembly type transport vehicle consisting of a connecting rod with a roller whose upper end is located slightly higher than the rail surface.
